Patents by Inventor Hung-Ju Wei

Hung-Ju Wei has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20150024695
    Abstract: Several multiband transceivers are disclosed. An exemplified multiband transceiver supporting different bands has a transformer, an inbound switch circuit, and an outbound switch circuit. The transformer has input ports on a primary side, and output ports on a secondary side. The input ports are direct-current isolated from and magnetically coupled to the output ports. The inbound switch circuit is configured to connect one of the input ports with an RF signal source for signal transmission. The outbound switch circuit is configured to connect one of the output ports with a RF output load. Optionally, an input tunable capacitor is configured to shunt with the effective inductance of one of the input ports and form a LC tank for band selection.

  • Patent number: 8822852
    Abstract: A rotary switch with multi-level is disclosed. The rotary switch includes a rotary base that drives the first conductive sheet to rotate with the second conductive sheet when the rotary shaft is rotated, and the second conductive sheet leaves one of the conductive contact elements; the position end of the second conductive sheet is pressed by one positioning surface during the rotation, and the second spring stores energy; the second spring then releases the energy to the fourth end of the second conductive sheet, and the position end of the second conductive sheet slides on one positioning surface until the position end of the second conductive sheets is positioned solidly between two positioning surfaces; so that, the material cost in production can be lower down, and life time of the rotary switch can be increased.
